85 Ceti is an older Flamsteed designation[8] for a star that is now within the borders of the northern constellationofAries,[9] the ram. In the present day it is known by star catalogue designations such as HD 16861 and HR 797.[7] It has an apparent visual magnitude of 6.30[2] and is approximately 410 light-years (130 parsecs) distant from the Earth. This is an A-type main sequence star with a stellar classification of A2 V.[3] It has 2.4 times the mass of the Sun and shines with 48 times the Sun's luminosity. This energy is being radiated into outer space from the star's outer atmosphere at an effective temperature of 8,810 K.[5] This heat gives it the white-hued glow of an A-type star.[10]
